Claims.

This invention relates to improvements in tens transfer mechanism formachines such as registers, adding machines and the like.

An object of this invention is to provide a machine of the abovecharacter which will be economical to make, both from the standpoint oflabor and materials used, and wherein the material is so disposed as toprovide strength without unduly heavy construction; which is simple,practical, and durable in use; which may be quickly and easily operated;which may be readily taken apart for purposes of replacement or repair;which may embody parts manufactured from relatively light andinexpensive materials; which will accurately register the sums oramounts entered thereon; and which, as applied to a cash register, orthe like, will provide an accurate and complete record of each sale ortransaction. Other objects and advantages will be in part obvious and inpart pointed out hereinafter,

Figure 16 is a view similar to that of Figure 15 but with certain partsin different relative positions; and

Figure 17 is a fragmentary rear view in elevation showing thearrangement of accumulator actuating cams and others on the shaftprovided for that purpose.

In operation of a machine of the type shown in Figure 1, for example, asfor recording or registering the amount of a sale, the user pressesinwardly on keys representing the number or amount to be entered on theregister. This places said keys and certain tripping devices inactuating position. The indicating, totalizing and printing mechanism,if any, of the machine is actuated by suitable means such as crank it,which is stopped after two turns.

Movements of the mechanism as crank it is turned may conveniently bedivided into four stages. During the first stage, certain parts of theadding mechanism or totalizer are moved to operative position. Duringthe second stage, the adding mechanism takes up the new amount or numberset up on the amount keys and the new total is transmitted to thetotalizer wheels. At the same time, the indicator wheels are actuated toindicate the number or amount registered,

During the third stage, the printing mechanism, if any, is actuated toprint the registered number or amount on a roll of paper or other recordsheet. During the fourth stage, the tens transfer devices carry overaccumulated ten values from each individual totalizer wheel of a lowerorder to the wheel representing the next higher order of digits.

As shown in the drawings, a fixed shaft 2! (Figures 1 and 2) issupported by side walls A and B. Crank l6 turns freely on the right-handend of said shaft where it is held in position by a headed bolt 22(Figure 1), threaded in the end of shaft 2|. The hub of crank it haslugs, as 23, which interlock with slots 24 and 25 (Figure 2) in the hubof a crank gear 26 also loosely mounted on shaft 2| to rotate said gearwhen crank I6 is turned. For the purpose of substituting a power drive,for example, crank 16 may be detached from shaft 2! by removing headedbolt 22.

In operation, crank gear 26, which has twenty teeth, turns clockwise asviewed in Figure 2 and meshes with an idler gear 27 which has ten teethand in turn meshes with a gear 28 which ary gears l9.

has forty teeth. Idler gear 27 mounted on a stud Zia extending laterallyfrom side wall B, causes gear 28 to rotate in the same direction(clockwise) as crank gear 25 and to make one full turn for each two fullturns of gear 26. The operating parts are so constructed and arrangedthat two full turns of the crank in a clockwise direction from itsdotted line position shown in Figure 2, complete the four stages ofoperation of the machine.

Referring to Figures 13 and 14, the secondary gear i9 is connected torotate clockwise with primary gear '32 by gear is only during the secndor additive stage. For this purpose gear '88 is mounted on a swingingframe pivotally supported between side plates 8 and E9 on shaft 58. Thisframe comprises spaced end plates I36 and I3? (Figures 1 and 4)triangular in shape and pivotally mounted on shaft 58 which. extendsthrough them at their upper corners (Figure l). Plates I 36 and i3? areheld in spaced relationship by transversely extending suitably placedspacing bars I33 and Mil (Figures 1 and 4). A fixed shaft E35 mountedtransversely in said frame supports the gears is which, during thesecond stage, connect the first four (from right to left) sets ofprimary and secondary gears respectively (Figure 11) and rotate freelyon said shaft lSS independently of each other. As shown in Figures 4, 5,6 or 7, slots MI and I42 in plates H36 and i3! of the swinging frame areprovided to permit a shaft 45 and a spacing bar hi4, respectively, topass through or across the path of movement of parts of the framewithout interfering with its pivotal movement. Spacing bar I44 acts as astop a ainst which portions of the gears 73 on shaft I39 abut when saidears are held in disengaged relation to the primary and secondary gearsby suitable means, as a spring I43, Figure 8, connected to plate I36 ofthe frame and to supporting plate 18 to bias the lower end of said frameoutwardly.

Referring to Figure 2, which shows portions 'of devices for actuatingsaid frame and gears '58 thereon, cam disc M, which rotates 360 duringthe four stages of operation. has a peripheral cam I46. At the beginningof the second stage, said cam i l-6 engages an arm Ml secured to a shaftI 5!! which has end portions journaled in and extending throughsupporting plates 48 and .59 and which carries cam arms I 88 and I49(Figures 1 and 4:). A lever arm 552. Figure 8, is secured to the leftend of shaft I59, as viewed in Figure 1, at the outside of supportingplate 48. the free end of this lever arm and the other end to support ngplate 58 (Figure 8) normally biases shaft I59 and cam arms Hi8 and I69in a neutral or inoperative position (Figure 4).

When shaft I59 is r cked b cam I48 engaging arm I i'I. cams I 38 and I49swing inwardly a ainst spacing bar Hi5 a d deflect the frame whichcarries gears l8 to the position shown in Figure 5, wherein the partsare shown positioned at the beginning of the second stage with gears 18in mesh with primary gears 12 and second- This position is maintainedthrough the second stage (Figure 6), i. e., while cam Hit continues toengage cam I41. At the end of the second stage, cam M5 disengages and Aspring I5i having one end connected to i secondary gears and remain sodisengaged during the two remaining stages of each complete operation.

Figure 1 shows four ets of amount keys and one set of clerks keys. Eachset of amount keys is connected to actuate a totalizer wheel by atransmission train, Figure 11, comprising among other parts a pawlcarrying disc, as Figure 32, a primary gear, as 72, Figure 13, and asecondary gear, as it (Figure 14). Ehus, for example, amount key set ii, third from the right (Figure l), is connected to actuate totalizerwheel 65 through a train identified in Figures 11 and 17 at E55.Accordingly, gears '85 for connecting the primary and secondary gears ofthe four numeral controlled trains are provided only for the four amountkey sets 3, 5i and 6d.

The primary and secondary of transmission train E537 (Figure ii) are,however, not connected by a gear '58 and act individually. The secondarygears of trains i5! and are also not controlled from any tabulator keys,but operate only to add or accumulate, on wheels 59 and ltdrespectively, Figure 1, unit values representing tens of the next lowerorder of digits accumulated on the totalizer wheel next to their right.The pawl disc 68 and primary gear "5'2 of train l5l are however used inproducing a printed record along with a number record, if desired,corresponding to indicia exposed on the clerk keys or to a registerednumber as it ap pears at the top of the register.

During operation, every time a totalizer wheel passes from. 9 toO,reaoling, or completes its 360 turn, it is necessary that theaccumulated ten value he carried to the next totalizing wheel thereaboveas a unit of the next higher order. For example, if the unit wheel 6'5last to the right, Figure 1, shows a 9, and a is registered on themachine, the unit wheel is turned to register The accumulated values often is taken up on the second or tens wheel which is moved a distanceequal to one gear tooth so that it registers 1. Accordingly, mechanismis provided whereby each totalizer wheel is so connested that the nexthigher totalizer wheel moves one place (unit) every time a totalizerwheel of lower number order is rotated 360 or past 0, independently ofwhether or not angular movement representing another value is impartedto said wheel of higher order by operation of a corresponding amountkey, As the totalizing wheels are connected to operate with thesecreleases arm MT and permits spring i5I to reondary gears, tenstransfer mechanism includes devices connecting each secondary gear withthe secondary gear of the next higher order to rotate said gear onetooth whenever the totalizing wheel of lower order completes its 360 orpasses 0.

Accordingly, each secondary gear, as it), except that of the highestorder of numbers, as that shown furthest tothe left in Figure 11, hasfour pins projecting laterally to the left thereof to coact withmechansm to be hereinafter described. As the devices for thusoperatively connecting adjacent secondary gears is substantiallysimilar, the description will be limited to that connecting secondarygear "id (Figure 9) to secondary gear 19a of the next higher order andpositioned to the left thereof. I

Referring now to Figures 4 and 8, each of the secondary'gears includingl9 and 'lt a has forty teeth; and gear it has pins EM, 252, 253 and 254projecting to the left as viewed in Figure 9, adjacent to every tenthtooth. These pins are positioned to synchronize in operation with thecompletion of each successive rotation cycle of numerals on thetotalizing wheel 61, Figure l, which is actuated gear 82, Figure 4,carrying ten teeth, so that, as totalizing wheel 61 passes the zeropoint, one of the four pins is brought into position to operate a latch,generally identifled at 255 (Figure 8).

Said latch 25?: is mounted for vertical reciproeating movement on shafts256 and 251, Figure 8, extending transversely across the machine andjournaled in side walls A and B, These shafts have annular guide grooves258 and 259 therein; and latch 255 has longitudinal slots 268 and 25!extending inwardly from its lower and upper ends respectively whichengage said annular grooves 258 and 259 to hold the latch in uprightoperative position and slidably movable in the said grooves. A head 262of latch 25a provides a cam edge 263 which extends across the path ofmovement of the pins 25!, 252, and 254 on secondary gear '38.

Referring to Figures 9 and 10, a latch lever generally identified at 256is pivotally mounted on shaft 25'? adjacent reciprocating latch 255. Theupper end. of lever extends outwardly to the right (Figure i0) and has alaterally projecting lug 26% extending to the left (Figure 9). A spring258 connecting lug 265 to a pin 261 on latch 255 biases the upper end oflever 264 to the right (Fig-tube l0) and its lower end to the left toengage a cam slot 265 in shaft 255. This spring also biases latch 255toward raised position wherein the bottom of its slot 25! (Figure 4) isheld yieldingly against shaft 251, Extending to the left of latch lever284 (Figure 9) is a lug 269 normally bearing yieldingly on the outeredge of latch 25:: below a. notch Z'ill therein. When said latch 255 ismoved downw y, as hereinafter described and as shown in Figure 8, lug269 drops into said notch 21?? to releasably hold latch 255 in its lowerposition.

Latch biased upwardly by spring 268 normally positions cam edge 2E3 inthe path of the pins on secondary gear l9, as described. When zero pointa totalizer wheel $1 is passed during the second or additive stage, oneof the trip pins, as 255 on gear 9, strikes and rides over the cam edge'hereby depressing the latch 255 to its said lower position in which itis releasably held by engagement of lug 259 with notch 210 (Figure 8)until released, as hereinafter described.

Latch 255 a hook 21! extending to the left (Figures 4 and 8) and which,when said latch is in upper position, engages pin 286 on a pawl arm 232to normally hold pawl 213 out of engagement with the teeth of secondarygear 19a (Figure l) Pawl arm 212 is pivotally mounted at 214 on anactuating lever 215; and a spring 216 secured thereto and to actuatinglever 215 biases said pawl toward the teeth of secondary gear 13a. Whenlatch 255 is moved downwardly b a trip pin, as 25!, Figure 8, ridingover cam edge 263, as previously described, the hook Z'll disengages pin23G permitting pawl arm 212 to rock and carry pawl 213 into operativeengagement with teeth of secondary gear 190, (Figure 8). The latch lever254 now releasably hold reciprocating latch 255 in its lower positionuntil the fourth stage, and thus prevents hook 21! of latch 255 fromreengaging pin 280 under the following circumstances. If, during theadditive operation just described, the next gear, as 19a, is also ro- Ihigher order.

tated to register a key added amount on a corresponding totalizer wheel,it is clear that the pawl 213, now released for transferring a ten valuefrom gear 19 to gear 19a, will be ratcheting on the teeth of said gear19a to the extent that the latter is rotated in the second stage. If,under these circumstances hook 21! were permitted to return to upposition immediately after being depressed by the passage of pin 25i ongear 19, said hook would re-engage pin 28%, or pawl arm 212 would bejammed while vibrating (due to said ratcheting during the additiverotation of gear 1%). This undesirable result is prevented by holdingactuated latches 255 and their respective hooks 21! in depressedposition until the second stage is completed. Thus, both the additiveoperation and the later transfer operation of any affected gear 19a areprotected against failure to function under the circumstances described.

Actuating levers 215 carrying the pawl arms 212 are pivoted in spacedrelation on a transverse shaft 28I supported at it ends by the sidewalls A and B and are individually rocked counter-clockwise, Figure 8,by cams, as 282, 2%, secured in longitudinally and angularly spacedrelation on a transverse shaft 283 journaled in side walls A and B. Eachlever 215 is biased toward engagement with the cam surface of a cam, as282, by a spring 288 connected at one end to transverse bar 289 (Figure8). Shaft 283 isrotated 360 during the fourth stage of operation, whichswings the cams, as 282 in succession against and across the rearsurfaces 284 of levers 2l'5 moving them counter-clockwise, Figure 8. Itwill be un derstood that the cam hereinabove referred to are arrangedwith all their cam faces disposed at one side of shaft 283 within anangle of 180". This advances pawl 213, now engaging secondary gear 19a,suificiently to move said secondary gear 19a an angular distance of onegear tooth and thus, by previously described transmission means, toadvance the corresponding totalizer wheel one space in addition to anyadvance made during a previous stage of the same operation.

During the second stage wherein the secondary gears 19 actuate totalizerwheels to add a number set up by previously depressing one or moreamount keys, the trip pins, as 25!, etc., on various of the secondarygears 19 may move into position to engage and depress latches 255 andrelease the pawl actuating levers 212 so that pawls 213 engage thesecondary gears 18a. During the fourth stage, all the actuating levers212 are operated by the means above described so that, if any pawl 213then engages a secondary gear 1%, that gear is moved a distance of onetooth; and the corresponding totalizer wheel is advanced one number orunit.

Referring to Figures 4, 8 and 1'1, the cams, as 282 and others on shaft283 for actuating levers 215 are secured in spaced and angularlystaggered relationship on said shaft 283. Thus, cam 282 through whichaccumulations of tens on the unit totalizer wheel are added as units tothe tens totalizer wheel is positioned so that it strikes itscorresponding actuating lever 215 a predetermined interval before thenext cam 290 engages the next actuating lever 215. Thus, during thefourth stage, each actuating lever 215 after the first in order operatesafter the preceding lever. This spacing is important because, if theaccumulated unit of a given order happens to be the tenth, theaccumulation continues into the next Thus, if the totalizer shows 9999tion. During the first 180, link 3% rotates gear 3i)! clockwise, movingscrew 3% to the position indicated by the dotted line Bil ie. During theremaining 180 rotation of gear 28, link 368 rotates gear Sillcounter-clockwise back to its original position. Gear Sill meshes with agear 303 mounted at the outer end of cam shaft 283 (Figures 2 and 17) insuch a manner that during the clockwise movement of gear 3536, Figure 2,gear 3&3 turns freely on shaft 283 counterclockwise but, during thecounter clockwise movement of gear 38! that is, during the fourth stageof operation, said gear rotates clockwise and rotates cam shaft 283 tomove the actuating levers 2'l5 by means of the cams, as 282 abovedescribed and for other purposes hereinafter set forth.

shown in Figures 2, 3 and 17, devices for effecting this mode ofoperation of shaft 233 include a disc are connected to gear 3513 whichrevolves freely on shaft 233. A lever 399 is pivoted to disc 308 at Silland biased toward shaft 283 by. a spring 3!! secured to disc 303. Lever399 has 9, lug extending inwardly and engaging shaft 233 which isprovided with a shoulder or detent 35?. In operation, during the'firsthalf turn of gear 28, disc 36% rotates clockwise, Figure 3, slightlymore than 360 and lug 3335 merely rides freely, clockwise, Figure 3,overthe surface of said shaft 283 until it. drops in behind shoulder 3M.When disc 383 reverses with gear 363, as

during the second half of the full turn of gear tact with the peripheryof disc 3H2 by a spring 33% secured to end wall A and the lever 3%3. Inopera ion, when lug 3% is sliding over shaft 283, rolle: restsyieldingly in notch 351 on the periphery of disc 352 preventing rotationthereof and of shaft tively turned in the opposite direction as in thefourth stage, roller 3E5 follows the peripheryof the disc 2-322 whichturns withit until roller 3l5 engages in notch til at the end of theregistering operation.

During the fourth stage when shaft 283 is actuated, the latch levers 254holding reciprocating latches 2555 (Figures 8', 9 and 10) are releasedby rocking movement of shaft 2% (Figures 10 and 1 annular grooves 258 ofwhich engage lower ends of latch levers 2%. A portion of bottom surfaceof each annular groove 258 is cut away to present a straight or flatbearing or camming surface normally disposed in the position as shown infull lines, Figure 10, where it remains until deflected to swing lever266 outwardly (right) for disengaging detent 259 thereof from notch 2'59in latch 255. Rocking movement of said shaft 256 from the normallatching position shown in Figures l, 8 and is produced by a When theshaft 283 is posi crank 325 secured thereto and having its free endriding on the periphery of a disc 32% secured on shaft 283 (Figures 15and 16) and biased into engagement therewith by a spring 32 la connectedto crank and to side wall A, as by a pin 32th, Figure 16. Disc Gil has aperipheral recess forming a reentrant cam edge 322 adapted to engage theend of crank 32% at the end of each complete operation of the machine.With the parts remaining normally in this position as seen in Figure 15,the cam surfaces 2&5 of shaft 256 exert no camming action on the ends ofthe latch levers 264; and said levers remain in the initial normalinoperative position shown in Figure 4 until latch 255 is depressed,whereupon said levers take the locking position shown in Figure 8 and infull line in Figure 12. However, during the fourth stage when disc 32%rotates 360 clockwise, Figure 16, with shaft 285, the free end of crank326 rides up out of engagement with cam edge 322 and onto the peripheryof disc 32!. This imparts slight rotation to shaft 256 so that the camfaces 2 in the grooves 25% thereof, wipe against the lower edge portionsof the latch levers 25 5 causing them to move outwardly to the extendedposition shown in dotted lines, Figure 10, to release the latches .255.At the end of the fourth stage, the free end of crank sze re-engages there-entrant cam edge 5322 which enables shaft 256 to rock back to itsinitial position and permits spring 253 to return latch levers 2% toposition to again engage the latches 255 when they are again depressedduring the next second stage.
